I had the swingarm off to strip & paint it, and also installed a new chain and sprockets. When I put everything back together the rear brake mechanism is rubbing on the frame and I can't figure out why. It was pretty pronounced while up on the center stand but I figured it would go away when back on the ground. It's a bit better, but it's like it rubs on the frame as it goes past it and then breaks free resulting in very unsmooth application of the rear brake. I'm about 90% sure it didn't do this before, but also I was unable to ride this bike until now. What should I be looking at? I don't see anything noticeably missing, and I only unbolted the wheel end parts required to remove the swingarm, I did not remove anything besides the foot pedal on the bike side.
